[ Sorry, I thought my setup was in my profile and should have been displayed under my name. ]
I have an original Vantage Pro console setup, and I have an ISS set to station 4, a remote anemometer on station 2, and I'm retransmitting to a WeatherEcho Plus on station 8. The reason the numbers are so weird is I've been switching stations in an attempt to find a setting that would improve performance. Nothing's helped so far, and my Weather Echo is still offline (it had been working on station 1.) I believe the station numbers represent actual frequencies and not just station ID numbers, but of course I could be wrong about that.
The ISS is where I notice the bulk of my problems. The console reception is very spotty. The symptoms are: it's OK for about the first month after changing the CR123 battery in the ISS, but after that night reception gets bad and progresses to worse. Davis replaced my ISS board once, but the symptoms were similar.
I'm pretty sure part of the problem is the ISS is at a very steep angle to the exterior wall of the house -- it's almost straight in line off the end of the wall -- so a direct line of sight isn't possible, and my estimate at a straight line would likely pass through at least three or four wooden studs. It's ordinary masonite siding over a foam backer board.
I seem to always have fairly good reception from the anemometer, which is mounted on the roof. A straight line shot from the anemometer would pass through the fiberglass shingles and roofing, a ceiling, a kitchen cabinet, a wall and a wooden bookshelf (full.)
My cordless phones are 2.4GHz (I replaced the 900MHz phones.) I replaced my 900MHz cordless headphones with a Bluetooth pair, just in case that base emitter ran even when the TV was off. I have an 802.11b/g base station. Other than that I have no other deliberate sources of RF energy. And my neighbors aren't especially close. The PC is near the Vantage Pro console, of course.
I do have a 500KV high power line running east-west about 50 feet to the north of my ISS (and some 50 feet up in the air.) And yes, I have played with neon light bulbs in my back yard near where the ISS is. AFAIK, 60Hz lines shouldn't interfere regardless of voltage.
What I'd like to do is run a cable to the antenna from the console, so I could keep the console near the computer and mount the antenna in a better place (perhaps the top of the bookshelf, or even outside under the eaves.) I've seen 900MHz "ceiling mount" antennas that would allow me to place it in the middle of the room, giving me a better shot through the wall to the ISS. They also might have a slightly improved gain over the stock antenna.
Another option, of course, would be to find a way to get 110VAC to a transformer outside near the ISS. But that's digging and wiring and I don't want to go that route, especially for a "wireless" system. I suppose I could hang an inductive coil on the ISS's post and leech off the power line!
